I'm also running a 140/90 15 without any issues. In fact my speedometer is closer to being correct now.

If you can put a 140 80 15 on, you can get the 90 on.  If getting any tire on the rim and the tube stem through the hole stumps you, no, you won't be able to put it on....

I'm running a 140/90-15 Pirelli MT66 Route tire that I like a lot, much better than the original IRC.  The only drawback is that it makes the second-third gear shift point a bit higher mph which is inconvenient on the streets I ride.  By the way, this Pirelli is not only taller but also wider (152mm actual width), heavier, and stiffer.  It was a chore getting the tube with a 90° stem in and the tire on, but I did it--you probably can as well.  I just put the Pirelli front on yesterday, and like it so far.  These are in short stock around the country; it took almost 4 weeks to get it from a local shop that orders through Parts Unlimited/Drag Specialties (same outfit, two names).

150 is how wide it is, 90 is how tall and 15 is how many inches the wheel is.

150 is how wide, 90 is ratio height to width, 15 is wheel diameter.  In other words height is 90% of 150mm for our 150-90-15.

I also have a 140-90-15 kenda challenger, which replaced a 140-90-15 cheng shin which replaced the stock 140-80-15.  no problems with the bigger tire.  it fits fine, looks better and gives a slightly higher top gear ( not enough higher)

i have to admit it took at least 3 tries the first time i changed though

1.  whoops pinched the tube #^&%#@!!!

2.  whoops! that arrow that says "drive" is on the tire backwards! #^&*%$!!!

3.  whew, finally!

I had a Metzler 140/90 put on by a bike shop. They didn't have any problem with doing it, told me that it was not a problem.

For low prices in Ottawa you generally have to stay away from the dealerships, unless you've got a buddy working at one who will give you a deal.

If you want to buy local get in contact with Jon @ Hybrid Racing, he will also mount tires not bought from him unlike some dealerships. Jon's prices are usually much less than the local dealerships.  http://www.hybridracing.ca/ContactUs.asp. I think he charges $40 out-the-door for two tires off of the bike, not sure how much for ride-in service.

If you're going to mount the tire yourself, or buy elsewhere and let Jon mount it, for low price on a quality tire Pete's Superbike http://www.petes-superbike.com/en/magasin/ out of Quebec has Metzeler ME880 in 140/80-15 for $176.95, 140/90-15 for $164.95. Shipping is cheap, about $20. Pete's also has Dunlop D404 140/90-15 for $93.95.

JC Whitney out of the US is another option, they have a flat rate shipping charge for tires and UPS isn't involved so the fee when you checkout is the fee you should be paying... most American online sites use UPS or FEDEX which tends to lead to insane US-to-Canada shipping rates...
